Pembuatan Kompon Karet dengan Bahan Pengisi Arang Cangkang Sawit

The objective of this research is to get the best formula in produced rubber compound and known the appropriate composition of palm shell charcoal by sol gel process. The design used was complete randomize design, consist of 2 factors : 3 (three) variations of treatment in palm shell charcoal particle size (ACS) and 2 (two) variations of treatment for the filler (ACS), with 2 (two) times repetition. The first factor of palm shell charcoal by sol gel process is a follows : A = range 40-60 nm particle size, B = range 80-100 nm particle size, C = 200 mesh particle size. The second factor is filler variations (ACS), namely C1 : ACS 20 phr, C2 : ACS 40 phr. Parameter tested cooking time Tc10, Tc90, modulus, density, flex resistance and compression set . The result showed that the best treatment is a combination of formula number 4 ACS nano particle size ranges 80-100 nm and 40 phr filler ACS which characteristic of the rubber compound cooking time Tc10 7 : 05 minutes , Tc90 17 : 40 min , modulus : 17 % , density : 1 g/ml, flex resistance : no cracks and compresion set 22%
